Description
Technical field
The present invention relates to a kind of for connecting at least one twisted wire of the feature with preamble part as claimed in claim 1
Contact sleeve.
Background technique
This crimp contact comes from such as 102013203796 A1 of DE.In addition, from 2009/119514 A1 of WO
Know crimp contact.
Electrical connection and terminal clamp also come from such as 3,634,099 2003249284 A or WO 2009/096590 of C, JP of DE
A1。
Specifically, have the electronic crimping contact device of the groove extended along arrowhead form from DE
102013203796 A1, the groove are used as the fixation device of cable end to be contacted.
Summary of the invention
The contact sleeve according to the present invention for being used to connect at least one twisted wire, contact sleeve have relative to center line
In the groove extended on two of the arrowhead form crimping wings, groove is curved since center line and with the gradient being continuously reduced
Extend outwardly in each situation, the twisted wire has the advantages that fixed and airtightly contacts twisted wire.Twisted wire and un-flexed groove
It still substantially preferably forces together compared to the curved grooves extended in a manner of the similar wing.The extensive research of applicant has been displayed
This point.
Preferably, groove since center line and extends across the crimping wing, until the end away from the crimping wing reaches preset distance
Or until the end of the even up to crimping wing itself.
To a certain extent, groove is run in a manner of identical with pinion in wing mode.According to advantageous embodiment party
Formula has 83 ± 2 ° of an angle relative to center line in the gradient of the tangent line of the groove of center line, and the gradient of tangent line towards
The edge of groove and reduce, until it is formed and about 88 ± 1 ° of center line of end angle.On the crimping wing only edge during crimping
Short-circuit line advance centre line zone in, there is bigger groove gradient, be greater than during curly course along longer route row
Into crimping the wing outer edge on groove gradient.
Purely in principle, groove is formed as relative to center line asymmetry, i.e., the groove on side may differ from
Groove on the other side and extend.Particularly preferred embodiment provides groove and symmetrically extends relative to center line.
The formation of groove can be carried out in many different modes.Advantageous embodiment provides groove and is arranged on reception
The recess of the channel form of the crimping wing on the side in region and towards twisted wire.
Detailed description of the invention
Exemplary embodiments of the present invention are shown in the drawings, and are explained in greater detail in the following embodiments.
Fig. 1 shows the contact sleeve according to prior art with the crimping wing.
Fig. 2 shows the plan views of contact crimp region according to the present invention.
Specific embodiment
Contact sleeve shown in Fig. 1 has contact crimp region 10, for harness 10b to be pressed in wing 10a is crimped
Together, and there is insulation crimp region 11, the insulator for being fixed on twisted wire 12 for that will contact crimp region 10.Contact pressure
Region 10 is connect with receiving surface 12a.It together with crimping wing 10a is used to that harness 10b to be pressed in one with intrinsic known way
It rises.Attachment contact crimp region 10 is arranged to around the insulation crimp region 11 of the insulator of twisted wire 12.Insulate crimp region
11 surround and clamp twisted wire 12, and are consequently for fixed twisted wire 12 and its strain relief.
In plan view shown in Fig. 2, tool there are two crimping the wing 15a, 15b contact crimp region 15 include relative to
Center line 14 is arranged to symmetrical groove 13, and groove 13 is bent in a manner of identical with pinion in wing mode.Therefore, curvature
It is formed so that the tangent line of groove is at an angle of α S with center line 14 in the region of center line 14.Constant gradient it is reduced to crimping
The external margin of the wing 15a, 15b, so that the gradient of groove forms angle [alpha] E relative to center line 14 in the outer region.
The research of applicant has had shown that angle [alpha] S is preferably about 83 ± 2 °, and angle [alpha] E is about 88 ± 1 °.
Because this shape of groove is bent and has outside in the edge direction of the crimping wing 15a, 15b from center line 14
The curvature continuously reduced, so ideally can be pressed in together harness in the crimping wing 15a, 15b.Therefore, curved groove
Arrangement is taked into account the fact that, i.e., during crimping, the crimping wing 15a, 15b only advance in the region of center line 14 more short-circuit
Line, and longer route of advancing in the perimeter of the crimping wing 15a, 15b.Center line 14 is considered by the larger gradient of groove
Region in this shorter route, and crimping the wing 15a, 15b perimeter in crimping during advance it is longer
Route is considered by lesser gradient.Harness is most desirably contacted by the crimping realization of the curved groove, especially
The air tight contact of twisted wire cannot be realized by the groove extended linearly.
Curved groove is asymmetrically formed preferably relative to center line 14.However, can also mention in an alternative embodiment
It is provided with forming asymmetric groove, i.e., relative to the groove on the area a Ge Juan wing, providing on another crimping wing has different ladders
The groove of degree.Groove is impression, ripple or (for example) projects upwards in the side of harness simultaneously therefore that twisted wire is coarctate similar
Object.
Groove extends to the end away from the crimping wing up in advance preferably since center line 14 and across the crimping wing 15a, 15b
Set a distance, or even up to crimp the end of the wing itself.
